Abstract

A new algorithm is modified and applied for estimating mobile velocity for EDGE (enhanced data rates for GSM evolution) cellular systems. The algorithm uses normalized autocorrelation of filtered received signals to estimate the velocity of EDGE mobiles. The algorithm works well for both non-dispersive channels and dispersive channels including typical urban and hilly terrain propagation models. Simulation results indicate that the new algorithm is very reliable and effective for distinguishing fast and slow moving mobiles in EDGE cellular systems with both 900 MHz and 1900 MHz carrier frequencies.
